Changing how I use IP address with FreeBSD’s vnet – so IPv6 works

The vnet (network subsystem virtualization infrastructure) on FreeBSD is both a blessing and a curse. For me, it isn’t working well with IPv6. I’ve hit issues with pf (since solved, I’m sure). It’s a useful feature but can be confusing. It helps to have lots of time to think about it and what you’re doing. …

Nagios 3: moving from nrpe 3 to nrpe 4 – what needs changing?

Yesterday, I noticed this message in one of the “daily security run output” emails which FreeBSD host can send out. I’ve used net-mgmt/nrpe3 for several years. It checks remote hosts and runs any number of predetermined commands and returns the results. It’s stable, highly configurable, and just keeps running. I had a look at the …

In this post: FreeBDS 13.1 The jail example I had a jail, similar to this: After the jail started, I could see both IP …
